Spiritual Surge of Transportation

[Trusk'our he/him]

The Surge of Transportation can be used to move between the physical and cognitive realms. Could it also be used to fully enter and exit the spiritual realm, allowing one the enter at one point and exit at another, essentially allowing them to teleport? The Oathgates seem to do something like this, so could an Elsecaller with enough practice do the same?

[Yumiya]

I don't really think so. The level of investiture they have would probably not be enough. The couple of times we have seen humans (not cognitive shadows or shards) do this is when they are INCREDIBLY heavily invested, Ascended invested levels. Even then they are not fully in the Spiritual Realm.

Can somebody travel to the Spiritual Realm, the same as the Cognitive?

Brandon Sanderson

Yes, but it's a very different experience. It is possible… You may have seen people do it...

Argent

As in you're not sure, or you're being obnoxiously vague?

Brandon Sanderson

No...

Questioner #1

As in, you probably have but he's having trouble remembering it.

Brandon Sanderson

No no no... For instance, Elend burning atium and duralumin pulled most of him into the Spiritual Realm.

Argent

Oh, that's what happens there.

Brandon Sanderson

Yeah. He kind of got yanked into- You also have seen people Ascend with the powers and dip into the Spiritual Realm for a little bit.

Argent

So, Vin?

Brandon Sanderson

Yeah. But they could be on both, or either, or both at the same time. But you have seen Vin stick into the Spiritual Realm. And it happened to Sazed/Harmony...

Questioner #2

Oh! So is that where the gods live? Kinda?

Brandon Sanderson

Most of the bulk of the Shard's energy of being is contained in the Spiritual Realm, yes. Except for one notable exception!

Questioner #2

The <mists? mistwraith?>?

Brandon Sanderson

No.

Footnote: We now know that the "one notable exception" Brandon refers to at the end is the Dor, which is mostly contained in the Cognitive Realm.

 At another point he says that all things are one in the spiritual realm, that it is made up of connections and investiture. Being there physically would probably make you go a little mad to be part of everything at once. 

Does not really seem much like a normal Radiant skill. Going the cognitive realm is a little more realistic.
